Still working on my TR86. Have to replace or rebuild the covers that go over the rotors. NH want's about a grand for each. Anyone else replace or rebuild them. Local machine shop can roll the concavity but can't put the bends along the sides and claims you can't weld on an angle iron 'cause it will warp. Did find one shop that can do it but looking at other options. Need to replace the sprockets on the rotor drives too. Worn pretty badly and looks like sprocket and shaft are all one piece... not a good idea! Any help appreciated.
